This display apparatus includes an optical sheet, and a holding memberholding a peripheral part of the optical sheet. The optical sheet has a hooking partextended from the optical sheet. The holding memberhas a hooked partto which the hooking part of the optical sheet is hooked. The hooked parthas at least one movement-prevention partfor preventing the hooking partfrom moving. Thus, disengagement of the optical sheet from the holding memberand positional deviation of the optical sheet are prevented when heat is generated during driving of the display apparatus and the optical sheet undergoes thermal expansion.
